IMPROVEMENT IN SEEDING-MACHINES.

The Schedule referred to in`these Lettersatent and making part' of the sanne.

- To all whom 'it may conce-rn:

Be it known that I, Asrrnn. S. RABBIT, of Keeseville, in the county of,Essex and State of New York, have invented a 'new and useful Improvement in Seeding-Machine; and I do hereby declare that the following is a full and exact description of. the same, reference bein-g had to the accompanying drawing and tothe lettelsof'reference marked thereon.

This invention relates'lto that class of seeding-machineswhich is provided witln slides for the purpose of regulating the discharge of the grain from the hopper to the earth, and consists incertain detailswhich will be fully described hereinafter.

Figurel is a plan View of my improved seeder;

Figure 2, a vertical transverse section of the same and Figure 3, a' front elevation of the hopper. To enable others skilled'in the art to make and use my invention, I will now proceed to describe .fully its construction and manner of operation.v

A represents the axle of the machine, vwhich is supported by the wheels a c, one of lwhich isrigidly attached thereto andv the other madeloose thereon, in

the usual well-known manner.

B B represent shafts, which areattached to the axle A, and, extending rearwardly, form supports for the hopper-box D.

C represents drag-bars, the front ends of which are hinged to the shaft, as shown, the rear ends being provided with drill-teeth, in the usual manner.

c represents a covering-roller, which is attached to the rear ends of the drag-bars by means of any suit able connections. Its peculiarity consists in its shape,

it being constructed of twocone-frustums united at v their small ends.`

D represents thehopper, which is divided by parti` tions, it' desired, into any suitable'number of-compartments, and is provided with suitable orifices in its bottom-board, for the Adischarge of the seed.

These .orifices are provided with inclined edges' upon one side, to preventthe seed from being crushed by the movement of the slides.

E E represent slides, which are similar in their construction and operation, one of which, however, is 1 they are brought into such contact with the arms as Y slide-is first opened, or so moved as to uncover the orifices beneath or above it, and then closed again before the other slide moves. This result is accomplished bymaking the arms of different length, the long arm permitting the slide to turn upon-its pivot sndieiently far to uncover the orice iu one direction, while the short arm ,permits the return movement, but prevents further movement in. the other direction.

F represents a plate, which is secured to the front `side oi' the hopper by. means of screws passingthrough slots, as shown. It is'provided with suitable oriices, through which pass thearms cl e2.' By means of its slots, the plate is permitted to `move longitudinally, being operated, when desired, by means of the lever G. By this movement, the arms el e2 are drawn out of the line of movement of the'pinsupon the axle,

yand, consequently, when thus moved, the seedingv mechanism is rendered inoperative. vThe lcver Gis pvoted at g, and has attached toit arms h h', the' former of'which is attached thereto,

but the Itter is pivoted -to it and also to the hopper Anected bymeans of chains.

The lever G is held in position by means of any suitable devices.-

The operation is as follows:

'.'Ihc seed vis irstiplaced in the hopper,l and the mechanism driven to Athe ield, the lever G being, of/r course, so secured'as to hold the seeding mechanism out. of gear, and also to elevate the vdrill-teeth from the ground.' lVhen the field is reached, the lever is operated, to loosen. the lteeth and throw the seeding mechanism into gear. The field is now traversed in the usual manner.

The revolution ofthe axle causes its pins to engage with the bent ends of the arms attached -to the slides/ and, consequently, gives the latter the propel" movement.

Ihe upper slide is first so moved as to uncover the .'orifice'beneath it and permit the seed to fall therein. It is then .moved back to cover the orifice, and the lower slide is opened, and the seed falls into the,l

spouts beneath. The lower slide is then closed and the upper opened, 4the operation being repeated, of

' course, indefinitely.

Tt will be observed that the amount of seed delivered at each discharge is measured by the thickness of fi;he hopper-bottom and. the circumference of the orl ce.

The seed falling into the furrow iscovered by the following roller, which, from its peculiar shape, draws the earth' and presses it inV a pyramide] ridge` immedintely over the seed.

1f desired, the slides muy be operated from either end by means of a cem, in the usual well-known man- DCI.

Hoving thus fully'describcd my invention, i

That I claim as new, and desire to secure by Letters Patent, is-

1. The pivoted slides E E', provided with bent arms and slide F, ns and for the purpose described.

3. Thearrangement of the frame AB, drug-bars C,

ver G, when the parts are constructed as described, for the purpose set forth.
